Let me start off by saying, I love teppanyaki. I love the tricks, I love seeing the random things put into your food, you can try it at home (minus knife juggling) and I love the fun vibe! Benihana didn't really deliver or maybe my expectations were too high going in..
And so follows the tale of my experience...(dramatic music)...
I came here for a friend's birthday (about 12 of us), so it was a fun vibe already. We got the drinks menu right on time: the prices are ludicrous. I understand that a portion of the price you pay is for the entertainment (juggling, etc.) ...but if I'm going to pay $70+ for a steak, I'm going to Ruth Chris' (awesome steak btw). I opted for the sushi tray, which was mediocre-to-above average sushi, except it cost almost $30 for 6 pieces of sushi: no juggling required here. Of the 12 of us maybe 5 ordered the non-juggling food options, and the servers spend the entire evening eyeing us down ... /sarcasm fun times /end sarcasm.
I will probably not be coming back. It would have been a fun little place to show out-of-town friends, but given the rude behavior.. I'm going to pass.
TL;DR: Slightly above-average food + entertainment. You're paying for the entertainment. Servers co-relate what you spend on how well they will treat your group. Not returning.
